In this study, a durable superamphiphobic nano-silica and epoxy composite coating with good environment resistant was successfully fabricated. Fluorinated nano-silica with low surface energy was prepared by in situ sol-gel method, which can be stably dispersed in the solution. Applying fluorinated nano-silica dispersion as sheath and epoxy solution as core, fluorinated nano-silica/epoxy superamphiphobic composite coating was prepared by a coaxial electrospraying method. Fluorinated nano-silica with uniform nano-size was distributed evenly on the micro epoxy particles, showing a special micro-nano hierarchical structure. Nano-indentation shows evident improvement in modulus and hardness of fluorinated nanosilica/epoxy composite coating than that of raw epoxy. In addition, durability of the superamphiphobic coating was assessed by performing harsh chemical environments immersion and scotch tape test. (C) 2017 Elsevier B.V. All rights reserved.
